I don't 'coupon' like some folks do. It's ridiculous. But I still do what I can to save money at the grocery store.
Enter: The Kroger App (disclaimer, I have no idea if other stores have this type of thing, but Kroger does and I love it)
Each week I need groceries (which isn't that often really), I open up the Kroger app on my phone. It has the weekly specials in it. AND coupons. Generally I get my list together before checking the ads, but sometimes I have a general idea of what I need, like some fresh veggies, and see what they have.
The nice thing about this is you can add the item to "Your List" and it gets organized based on the areas of the store. You can pull up your list and it's in an order of sorts that makes sense so you're not running back and forth in the store.
The best part however, is that the coupons get loaded directly to your frequent shopper card. When you scan the card, if you have a coupon for an item it automatically deducts it. You don't have to cut the coupons out, and such.
Super nice too, I can open the app while waiting in line at the post office, while on the bus, over my lunch break when I don't have homework. It's portable coupons folks! I love it.
Bonus tip: When you get your receipt, check it for the survey code. Each survey you complete gives you 50 fuel reward points, and with the cost of gas these days every little bit counts!
